With Zhang Ran's thoughts, in front of him, a crystal slightly larger than a ping pong ball and with some roughness around it suddenly appeared, and on the surface of this crystal, there were still some traces of blood from the Demon Eye and other broken tissues

After taking out this piece of Demon Eye Monster Spirit Crystal, Zhang Ran immediately took out a bucket of low-radiation water from the space box, and then carried out a simple cleaning of this crystal to remove the powerful corrosive blood on it

After completing the cleaning, a crystal with a pink-white color, a crystal crystal with a crystal clear surface, and a beautiful appearance appeared in front of Zhang Ran, which was the spiritual crystallization of the cleansed Demon Eye Monster

Although there is a large amount of radiation in the body of the Demon Eye Monster, ordinary people will have a serious illness or even die violently even if they come into contact with it, but the spiritual crystals condensed in its brain are pure and flawless, and there is almost no radiation, which also makes Zhang Ran can't help but be amazed, sighing at the various mysterious laws in the wasteland world

In the Black Eagle Company, a level 4 Demon Eye spirit crystal can also be sold for about 20,000 Black Hawk Coins, which is much higher than the purchase price of ordinary Level 4 mutant biological materials, and the sale price is as high as 50,000 Black Eagle Coins, and it is almost impossible to buy

Whether it was Zhang Ran or those ordinary evolutionaries, for this kind of treasure that could improve their strength, they would almost never sell it, but would keep it for their own use, and only those more powerful evolutionaries would sell low-level spiritual crystals that were useless to them

With a thought, Zhang Ran held this piece of Demon Eye Monster's spirit crystal in his hand, strange to say, although the texture of this Demon Eye Monster spirit crystal looked very hard, but after Zhang Ran's palm came into contact with it for less than a minute, its surface began to soften

Like a piece of butter at a high temperature, this piece of demon-eyed spirit crystals quickly turned into a mass of almost transparent and viscous liquid, which quickly burrowed into his body along Zhang Ran's pores

As soon as this viscous liquid entered Zhang Ran's body, it immediately brought a cool feeling, and then began to flow in Zhang Ran's veins, completely releasing the energy essence inside, and continuously strengthening Zhang Ran's body

There are three directions of this energy, of which about seventy percent are surging towards Zhang Ran's brain, strengthening Zhang Ran's spiritual power, the other two percent are surging towards Zhang Ran's vertebrae, and the remaining one is integrated into Zhang Ran's body

"Refining the spirit crystallization of the demonocus, absorbing evolution energy, evolution point condensation +3.21%, current progress: 17.64% (1/3)"

"Refining the spirit crystallization of the monocturn, the physical fitness is enhanced by evolutionary energy, strength +0.003, constitution +0.002, agility +0.002, spirit +0.051"

About ten minutes later, Zhang Ran had already completed the refining of the spirit crystallization of the Demon Eye Monster, and at the same time, the prompt sound of the chip sounded in his ears truthfully

"0.05 points of spiritual attribute increase, that's really good!"

Listening to the prompt sound of the chip, feeling the more powerful spiritual power in the sea of knowledge, Zhang Ran's face also showed a smile, and the corners of his mouth slightly arced

Although Zhang Ran's current abilities are all concentrated in the fighting domain, for an evolutionary who majors in the fighting domain ability, spiritual attributes and spiritual power are still very important existences, which can improve their observation ability, and at the same time, it can also improve their neural reaction speed and combat effectiveness, making their strength stronger

Not only that, for Zhang Ran, who has the "Tree of Evolution", he can obtain a new ability every time he advances, even if Zhang Ran's current ability is the fighting domain, but in the future, it is very likely that he can obtain the ability of the spell domain, the perception domain or the auxiliary domain, so the significance of spiritual power to Zhang Ran is even more important

"Although I won this battle, I also exposed my shortcomings! Even though I had a lot of combat experience before crossing over, this is a wasteland world after all, with all kinds of magical abilities, and my past combat experience and combat ability have helped me less and less!"

"In addition, because my combat power is higher than that of mutant creatures of the same level, my promotion speed is too fast, unlike other evolutionaries who have to go through life and death training and polishing to advance, which also causes my combat power to not keep up with my level!

After refining this demon-eyed spirit crystal, Zhang Ran was not complacent, but reflected on his battle with the demon-eye

With the improvement of Zhang Ran's physical fitness, his strength has also continued to improve, but at the same time, he found that his fighting consciousness is no longer enough to give full play to his physical fitness

For such a situation, Zhang Ran knew that this was not a good thing, and the rapid growth of strength was sometimes not necessarily a good thing, but would lead to a vain realm, which was not conducive to future development, especially in such a wasteland world full of dangers and respected combat power

Recognizing his own problems, Zhang Ran naturally had to make corresponding changes, but fortunately, Zhang Ran had the existence of a chip and could continue to conduct simulated battles to improve his strength

In addition, Zhang Ran also decided to dedicate a week to some additional physical training in order to completely adapt to his body

.....

A week later

During this week, Zhang Ran deliberately slowed down the speed of hunting mutated creatures, and instead spent more time mastering his body and strengthening his sense of battle

If he hunted with all his might, this week was enough time for Zhang Ran to successfully condense the second evolution point and take a new step towards the realm of a fourth-level evolutionary, but because he deliberately slowed down a certain speed, his evolutionary energy condensation level only increased by 70%, reaching 92.33%.

Although the acquisition of evolution energy has slowed down, because Zhang Ran has devoted more time to training, Zhang Ran's control of his body and combat awareness have improved significantly, and his strength has also increased by about one percent

What's more, during this week, Zhang Ran will spend about six hours training in the simulated battle space, simulating battles with those level 4 mutant creatures

Of course, Zhang Ran's main training objects are still the Demon Eye Monster and the Tyrant, compared to those mutant creatures that Zhang Ran has never encountered, these two mutant creatures that Zhang Ran has fought against are easier to simulate, and the corresponding simulation results are more realistic

After a week of training, until now, if Zhang Ran fights that Demon Eye monster again, then Zhang Ran will definitely not be as embarrassed as before, at least he will not be hit by the Demon Eye Monster's [Curse Technique], and he can kill it more easily

Very satisfied with the progress of his strength, Zhang Ran is also ready to go deep into the wilderness again, hunt some level 4 mutant creatures, test his battle results, and continue to advance to level 4 evolutionary
